Card game machine

Abstract

An object is to provide a card game machine capable of enhancing gameplay. A card game machine has a game board including a plurality of reader / writers configured to communicate with a semiconductor device which is mounted on a card and capable of wireless communication, and a control device connected to the reader / writer and configured to determine the position or orientation of the card or whether the card is put face up or down based on a signal from the reader / writer. By arrangement of a plurality of reader / writers and RF chips in the game board, not only data of the card but also signal strength can be detected, and the detailed position of an RF chip of the card which is placed on the game board can be specified.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a game machine. In particular, the present invention relates to a game machine using a card that has a semiconductor device capable of wireless communication.[0003]2. Description of the Related Art[0004]There are many kinds of card games. Typical examples are playing cards, karuta (Japanese playing cards), and the like. One type of card games is trading card games (also called collectible card games). As an example of techniques on a trading card that has a semiconductor device capable of wireless communication, Reference 1 is given (Reference 1: Japanese Published Patent Application No. H11-244537).SUMMARY OF THE INVENTION[0005]Trading cards are characterized by not only gameplay but also collection, and rare cards are sometimes traded at high prices among card enthusiasts. However, with the recent development of copy technology and the like, many clever imitations are produced, and sec...

Benefits of technology

[0007]In view of the above-mentioned problems, it is an object of the present invention to provide a card game machine which has high game expandability and which makes card forgery difficult.

[0010]Note that, although there is no particular limitation on the shape of the card, it is preferable that the card have a quadrangular shape or a quadrangular shape with round corners. It is also preferable that the semiconductor device capable of wireless communication, which is mounted on the card, be positioned not in the center of the card but in a given fixed position on the left, right, top, or bottom. It is more preferable that the position be in any of the four corners of the card. In addition, when the card has a quadrangular shape with round corners, the card can be made easier to handle.

[0012]It is preferable that the position in which the RF chip is fixed be a given fixed position on the card because it is possible to recognize not only the position of the card but also the orientation of the card, whether the card is put face up or down, and the like.

[0013]As described above, from information stored in the RF chip and detailed information on the position of the RF chip on the game board, the type, location, orientation, or a combination thereof can be recognized, which allows gameplay to be enhanced. For example, when the rule is that a first parameter is used when the card is put face up and a second parameter is used when put face down, even if the first parameter of a card has a small value, the second parameter is used when the card is reversed. Accordingly, a card with a first parameter having a smaller value can defeat a card with a first parameter having a larger value, which makes the game more exciting.

[0014]By use of the game machine of the present invention, the game can be played following the rule even if the rule is complicated, and not only can the rule be unified, but also the burden of remembering the rule can be removed. Moreover, the adjustment of the difficulty level of the game and the change in the type of the game can also be achieved by change of software.

Problems solved by technology

In addition, existing trading cards each having a semiconductor device capable of wireless communication are recognized one by one; therefore, there is a limitation on the enhancement for gameplay.
